The correct figure is the one with an ellipse slanting from its top-right corner towards the lower left and a thin arrow with a small solid head pointing to the lower left.

The question figure is split into four quarters by a vertical and a horizontal line. The top-left, top-right and bottom-right quarters each hold an ellipse lying along the diagonal from the centre outwards, with an arrow inside that starts at the centre and ends in a small solid head at the outer end. The bottom-left quarter is empty.

The design is symmetric about both dividing lines: the top-left quarter mirrors the top-right one, and the bottom-right quarter mirrors the top-right one. So the bottom-left quarter must mirror the bottom-right quarter: its ellipse runs from the centre (the top-right corner of the missing piece) towards the lower left, and its arrow points outward to the lower left with the same small solid head.

Two answer figures have the ellipse slanting the other way (from upper left to lower right), so they cannot fit. The remaining wrong figure has the correct slant, but its arrow has a thick shaft and a large hollow head, unlike the small solid heads in the figure. Only the figure with the thin arrow and small solid head completes the design.
